Value Collection 97091 Hex Head Cap Screw 7/16-14 X 4 in Grade 5

Product Description

The VALUE COLLECTION 97091 is a 7/16-14 partially threaded hex head cap screw manufactured from Grade 5 steel with an uncoated finish. At 4 inches under the head, this fastener follows UNC thread standards and meets ASME B18.2.1 and SAE J429 specifications. It is sold in packs of 25 and is suited for mechanical assembly, equipment mounting, and structural fastening applications across HVAC, plumbing, and general trade work. Licensed tradespeople and maintenance professionals reach for Grade 5 fasteners when moderate tensile strength is required and high-alloy hardware would be overkill.

This screw is appropriate for use in residential and light commercial mechanical assemblies where a standard UNC 7/16-14 thread pattern is called out. Typical applications include equipment base mounting, panel attachment, and bracket fastening on HVAC units, pump assemblies, and similar mechanical systems. The partially threaded shank provides a bearing surface useful in clamped joint connections where thread engagement only at the nut end is preferred. Pack quantity of 25 suits single-job or multi-unit service work without requiring a bulk order.

• Partially threaded shank allows clamped joint engagement with full shank bearing surface
• 4-inch length under head accommodates deeper stack assemblies and thick flanged connections
• Uncoated finish suitable for indoor mechanical applications or where field-applied coatings will be used
• Pack of 25 supports efficient single-trade or multi-unit service calls

Compatibility

Designed as a standard UNC hex head cap screw for use in any application calling for a 7/16-14 x 4-inch Grade 5 partially threaded fastener per ASME B18.2.1 and SAE J429.

Installation Notes

Installation is performed by qualified mechanics, HVAC technicians, plumbers, or electricians as appropriate to the assembly being fastened. De-energize and lock out all equipment before replacing or installing fasteners in mechanical systems. Use a properly sized hex wrench or socket to avoid rounding the hex head. Do not mix Grade 5 fasteners into joints specified for Grade 8 or metric-class hardware without verifying joint design requirements.
